` 13 claims. (c1. 93-1) This invention relates to the manufacture of confection sticks of tightly rolled up paper convolutions permanently adhering so as to constitute a non-splinterable support having an eii'ective degree of rigidity.

'I'he invention will be readily understood from the following description when considered in connection with the accompanying drawings which disclose a preferred embodiment of the apparatus for eifecting the manufacture of confection sticks.

In the drawings:

Figli. is a comprehensive view in the nature of a vertical section through apparatus for the manufacture of the illustrative confection sticks.

Fig. 2 is a vertical section showing a part of the illustrative apparatus on an enlarged scale.

Fig. 3 is a vertical section through another part of the illustrative apparatus in which the compacted stick rolls are transferred from the dry compacter to the second compacter which bonds `the outside paper convolutions of the rolls and mechanism.

Fig. 7is'a plan of the convoluter shown in l Fig. 6.

Fig. 8 is a front elevation of the convoluter. Fig. 9 is a detail view showing parts of the ,u convoluter and fumiicating its action in the form- `ing of the loosely woundfrolls.

Fig. 10 is a vertical section through the convoluter, indicating the manner in' which the loosely wound stick rolls arereleased to the I lcompac'ting mechanism.

InFig. 1 of the drawings the main feeding mechanism for delivering the paper fromfa roll toaan apparatus may be considered as indicated generally at A. This feeding mechanism delivers l fthe paper strip to a festooning mechanism loof which is subsequently formed into a loosely i vwound rollby the convoluting mechanism at D.

From the convoluting mechanism the loosely woundroll `is passed through the dry compacter E which delivers the rolls to the bonding or wet roll compacter F. The paper strip I3 is caused to be unwound in the direction of the arrow I2 from the supply roll II by the rolls I4 and Il of the main feeding mechanism. At least one of these rolls is continuously driven at constant speed and the rolls are pressed together so as to exert a suilicient grip upon 'the paper.

In order that the paper unwinding from the supply roll II may be maintained slightly vtaut between the supply roll and the feeding rolls I4 and I6, a friction brake is applied. This may consist of a flexible strip I3 xed at 20 and extending over the roll I I, with a weight 22 hung on the strip as indicated in order to maintain its braking effect.

Beyond the main feeding rolls I4 and I6 the paper is maintained in the festoon 24 by the floating roller 26 rotatably mounted on an arm 28 freely pivoted to a support 30 as shown in the drawings.

From the festoon roller 26 the paper passes through auxiliary feeding mechanism consisting of the rollers 32 and 34. These rollers are sufficiently pressed together to cause the paper to be gripped between them and intermittently advanced to the cutting mechanism C. The auxiliary feeding mechanism may be intermittently operated by a ratchet and pawl mechanism including the connecting rod 3i pivoted at 33 to the constantly rotating element 40 of the cutting mechanism. The connecting rod is pivotally connected at its other end to an arm 42 freely rotatable aboutthe shaft 44 upon which the roll 34 is mounted. A driving pawl may be associated with the end of the arm 42 near the pivoted connection of the latter with the rod 36 and a spring pressed pawl 48 mounted upon a fixed pivot at 50 may prevent retrograde movement of the roller 34.

'I'he auxiliary feeding rolls have a peripheral main feeding mechanism, and therefore while the rollers vof' the auxiliary feeding mechanism are .operativeythe festoon about the roller 26 is dei 'creased in length and that roller is elevated.

This may also be -referred to astaking up the slack in the paper between the constantly rotating main` feeding mechanism and the intermittently operating auxiliary vfeeding mechanism.

After the auxiliary feeding mechanism includingthe driven roll -34 advances `the paper. along the bedplate or cutting platform 52 a distance equal to the predetermined dimension of the pa..

per section, the driving pawl carried bythe arm 42 begins its retrograde movement and the auxiliary feed is therefore inoperative until the connecting rod 36 has completed its movement in that direction. During this time the main feeding mechanism including rollers |4 and I5 is constantly advancing the paper so that the festoon is increased in length by the weight of the freely rotatable roller 26.

During the paper advancing movement of the' auxiliary feed roller 34 the paper is advanced beyond the knife 54 to a position beyond the point at which the first floating roller 56 tends to engage the upper run of an endless belt 58 which drives the roller 60. This belt is so driven that its upper run moves in the direction of the arrow 62.

I'he distance of advance of the paper beyond the knife 54 is equal to the predetermined dimension of the section to be severed. When this advance has been completed the forward movement of the paper stops and the cutting mechanism is brought into operation. 'I'his cutting mechanism includes a crosshead 64 appropriately and accurately confined between parallel vertical guides so that the knife maintains a constant position with reference to the advance of the paper. The knife is fixed to the cross-head and the latter also carries a presser foot 66 fixed upon the lower end of a stem 68 which is freely slidable in aligned openings in the upper and lowerv supports 'l0 and 12 rigid with the crosshead. Between the lower support 12 and the rubber faced presser foot 66, there is a coil spring 14 for keeping the presser foot continuously urged downwardly from the cross-head. Thus, when the raised portion 16 of the constantly rotating cam 18 strikes the cam roller 80 the entire cross-head is moved downwardly. The presser foot, due to its location at a level below the lower edge of the knife 54 first engages the paper section which is stationary upon the cutting bed 52, and holds the paper fiat against the upper surface of the bed in order that it may be cleanly and accurately cut by the descending knife 54. As soon as the paper strip is severed and the raised circular portion 'I6 of the cam has passed out of contact with the roller A the crosshead with its knife and presser foot may be immediately retracted from contact with the paper section by a suitable spring which constantly tends to hold the roller A against the surface of the cam 18 and elevate the cross-head.

While a paper section is being severed by the knife 5 4 that part of the paper in front of the knife 54 is held approximately against the surface of the bed plate 52 by a guide 82.

It will be appreciated that while a paper section is being severed by the knife 54 that the leading edge of that section is pressed lightly against the upper run of the endless belt 58 so that the latter is constantly tending to advance the section in the direction of the arrow 52. Although this force is not suflicient to tear the paper or injure it in any way it is sufficient to immediately cause the severed section to be advanced when that section is released by the upward movement of the presser foot 56. Thereupon the severed section advances along the upper surface or upper run 58 of the endless belt toward the convoluting mechanism D and it is held flat against the belt 58 during this advance by the floating rollers 90, 92 and 94. 'I'here are enough of these rollers to maintain the paper section fiat against the top surface of the belt 58 until the leading edge of the section passes under the fixed guides 96 of the convoluter D. The

association of the roller 90 with the guides 96 is clearly indicated in Fig. 9 of the drawings, the paper section 98 being shown with its leading edge within the convoluting chamber |02 of the convoluter.

The fixed guides 96 of the convoluter are shown in plan in Fig'. '7 of the drawings and in side elevation in Figs. 6 and l0. These guides 96 are in the form of bars, and, in one embodiment, they are made of brass of in thickness. They have rearward extensions |04 and they are held rigidly in spaced relationship by interposed steel bars |06 which may be of 5% in thickness. 'I'he entire body of the guides 95 and the bars |06 are maintained as a rigid frame between side frame members |00 and ||0 by bolts ||2 and ||4 which pass through all these members as indicated in Figs. 6, 7 and 10 of the drawings. This frame is rigldiled and strengthened at is forward portion by the provision of the forward extensions |20 (see Fig. which have aligned openings to receive a rod or bolt |22. This bolt extends through all of the forward parts of the guides 96 and is encircled between the extensions by collars |24 which are of the same width as the steel bars |06. Thus the entire front end of the convoluter frame is strengthened when the bolt |22 holds al1 Inf the collars |24 tightly between the extensions The lower and forward portions of the guides 96 are similarly strengthened by a bolt |26 which passes through these guides and has spacing collars |28 tightly gripped between the successive guides.

The entire frame of the convoluter including the parts |04 and |06 as well as the side frame members |08 and ||0 is rigidly secured to suitable main side frame members in order that the lower surfaces'of the guides 96 may be maintained in their relationship to the endless belt 58 indicated in Fig. 9 of the drawings and the lower surface of the convoluter frame maintained in fixed relation to the upper surface of the belt 58 rearwardly of the convoluting zone |02. For a purpose which will later appear the lower surface of the convoluting frame rearwardly of the convoluter zone |02 is covered by a plate |30 havlng a non-metallic facing |32 bonded thereto. 'I'his plate is fixed -to the convoluter frame by stud bolts |34 as indicated in Fig. 6 of the drawings.

Laterally of the side frame members |08 and ||'0 of the convoluter frame there are bearing members |40 and |42 having aligned journal bearings |44 and |46 integral therewith. The members. |40 and |42 are rigidly secured to the convoluting frame as indicated in Fig. 7 and the journal bearings |44 and |46 receive the shaft |46 for convoluting rollers |50. These rollers may consist of rubber rollers forced onto the shaft |48 so as to be non-rotatably connected thereto.

The shaft |48 is arranged so as to be received within the notches or slots |52 between the upper and lower forward extensions |20 and 96 of the fixed guides of the convoluter. 'Ihis permits the entire convoluter roller assembly with the bars |40 and |42 to be 'readily detached for repair or replacement.

The convoluting rollers are arranged between the fixed guides 96 and the shaft |48 is so ing the yconvoluting chamber and is-jabc'aut tok rotated that the rollers have a peripheral speed which is slightly more' than that of the peripherall speed of the conveyor I0. Thus when the y peripheries of the rollers extend slightly within the confines of the convoluting chamber |02 the leading edge of a paper. section will not only be acted upon as indicated in Fig. 9 of the drawings to reduce the-frictional resistance to the advance of the section but the rapid convolution of the section will be also promoted by the continuous action of the rollers |00 upon the outer convolution of the paper section during its entire exposure to the action within the convolutlng zone.

Appropriate side frame members are secured to the ilxedframe of the convoluter so as to rotatably support a rod |00 which forms a pivot for a movable section of the convoluter indicated generally at |02 in Figs. 6 and l0 of the drawings.

This movable section has roll releasing guide' surfaces upwardly and rearwardly. inclined so as to initiate the curling movement of the strip 00 within the convoluting chamber |02 when the parts are in the relationship indicated in Fig. 9 of the drawings. The movable convoluter section also includes the aluminum spacers |10 as indicated in Figs. 7 and 8 and the entire assembly of the releasable guides |04 and the spacers |10 are secured together so as to form a rigid unit. For this purpose bolts |12 and |14 extend through all of these members, and one endof the bolt |12 beyond the assembly of the members |04 and |10 'affords a mounting for a rotatable cam `engaging roller |15. l

The cam roller |10 is periodically engaged by the raised surface |10 of the constantly rotating cam |00 to move the entire section |02 from its full line, or operative position.` to its dotted line or roll releasing position as clearly indicated in drawings. The cam |00 rotates in the direction of the arrow |02 and the raised concentric surface |10 of the cam is of such extent that the entire movable section |02 will be held in its roll enter it. At the .same time the releasedpaper roll is .moved forwardly by the belt` finto a contracting or tapered passage 200 above; the upper run of the belt. -This passage is formed by thefacing |02 and by a nxed plate 200 and the upper surface of the belt. The continuity of its taper is such that this passage decreases in depth to a position at the junction of the bonding beit 202 and the endless belt 00. This position is lndicated at 204 in Fig. 3 of the drawings. h

The lower surface of the e 200 is closely and accurately determined by the upper surface of the bedplate 200 along which the upper run of the belt 00 moves. This bedplate extends to close proximity to a pulley or roller 2li around which the belt l0 is trained and the surfaces of'the e 200 beyond the rearward end of the plate 202 are determined by ythe surface of the belt and the inner curved surface 2|0 of a metallic block 2|2 secured in fixed relation to the described Parts.

As the loosely wound rolls 220V proceed along thecontracting passageway 200 the number of convolutions in each roll is increased and pressure is maintained on the rolls. This action resultsfrom the relation of the depth of the passageway 200 to the diameter of the rolls as they pass from the convoluter and from the rolling up action resulting fromthe forward movement of the belt 00 while the opposite sides of the rolls are pressed againstthe stationary plate 200 and the inner and curved surfacesof the block 2|2.

. space between the belts 00 and 202 and forwardly releasing position long enough to permit the loosely wound paper roll to be influenced by the action of the endless belt so that it is moved out of the range of movement of the lower end |00.v Immediately upon the movement of the loosely wound roll beyond this :range the spring |00 acts to move vthe entire section |02 to its operative position wherein it cooperates with the iixed guides 00 and defines the convoluting chamber |02. The period of time during which the movable section is held in this operative position is determined by the circumferential extent of the inner concentric surface |00 of the cam |00. The spring |00 has one Vend secured to a clip |01 fast to the movable section |02 and its other end adjustably fixed to a bracket l|00 which is mounted upon a fixed portion l|02 ,of the supports for the apparatus. It will be understood that as soon as the movement of the `assembly |02 from its full line position to its dotted line position has released a convoluted paper roll from the convoluting chamber |02 that a succeeding paper section is approachof the toothed edge of the transfer plate- 230. This plate is fixed to the lower surface of the block 2|2 as clearly indicated in Fig. 3 of the drawings. It is secured thereto by fastening devices which pass through the openings 202.

The proper transfer of each paper roll from #contact with belt 00 to the bonding and sealing passageway 204 above the upper run of the belt 202 is promoted by the teeth 230 formed in the knife edge of the member 200. These teeth prevent excessive unwinding or expanding ofthe roll as it emerges from the passageway 200 and they cause the roll to be so gripped that the action of the belt 202 moving in the direction of the arrow 240 willinitiate the movement of the roll into the passageway 204.

'I'he lower run of the belt 202 is indicated in Fig. 1 of the drawings as in contact with a roller 242 for the purpose of supplying moisture or an adhesive to the surface `of the belt. This roller is mounted in fixed bearings so that it continuously passes through a body of fluid 244 within the receptacle V240. In this way a small amount of adhesiveor other uid is applied to the outer surface of thebelt 202 at a position near the point of transfer of the paper rolls from the passageway 200 to the passageway 234. Consequently the fluidy isapplied to each roll immediately after it emerges from the passageway 200, and while it is in contact with the teeth 230 of the member 230. This application of fluid takes place immediately after the expanding of the roll so that the fluid cangbe applied to surfaces of the roll which will be within the roll after it is sub-l the upper run of the belt 202 is held accurately in its desired relation to the lower surface of the plate 250 by the bedplate' 252 which extends from the forward pulley or roller 254 to the rotating element 256 about which the belt 202 is trained at the discharge end of the apparatus.

The action within the passageway 234 is similar to that which takes place within the passageway 206, but the rolls may be compacted to a greater degree and thus rolled to the desired dlameter of the ultimate product above the belt 202. The action of this belt also results in a bonding of the exterior convolutions of the rolls and when adhesive has been applied by the roller 242 the rolls are adequately sealed against unwinding when they emerge from the bonding passageway 234.

In Fig. l of the drawings the belts or conveyors 58 and 202 are indicated as driven by a motor 260. The belt 262 connects vthe motor with a counter-shaft 265 upon which the driving elements 261 and 269 are mounted -and a chain 21| is trained around the element 269 and a sprocket l 213 on the shaft 215.

The pulley 2li for the belt 58 is driven by a sprocket chain 266 trained over sprockets xed upon the shafts 264 and 268, and the shaft 264 also has fixed thereon a sprocket 28|, connected by a chain 282 with a sprocket 283 upon the countershaft 285.

The cam |80, controlling the operation of the convoluting mechanism may be driven by means of a chain 210 which is trained over the sprocket 290, on the shaft 285 and a sprocket 211 mounted upon the cam shaft 212.

Figs. 1 and V2 of the drawings also show the cam 18 for the cutting mechanism as driven by a belt 280 directly connecting the rotating elements upon the shafts- 212 and 219. It will be understood however that the driving connections referred to herein are merely illustrative and that the actual driving connections must be such as to above described.
